Package runtime DLLs for NuGet

[eXpl0it3r]

Include the CRT DLLs with the NuGet package fixing #409

• We can't link the CRT statically, as this would require us to link SFML statically, which would again trigger Joystick state does not update when polling events via RenderWindow on Windows #136
• We need to ensure to only ship DLLs that are part of the redist to adhere to Microsoft's license agreement

@JupiterRider Do you have an easy way to test a NuGet package without Redist already installed?
If so, can you given the following NuGet package a try?

I successfully tested the libraries in the Nuget package inside a blank x64 Windows 10 VM.

I used my own application which loads csfml-graphics.dll via LoadLibraryExA("assets/csfml-graphics.dll", NULL, LOAD_LIBRARY_SEARCH_DLL_LOAD_DIR | LOAD_LIBRARY_SEARCH_DEFAULT_DIRS).

Awesome, thanks for testing! 🙂
